Thermolec electric duct heaters are designed for use in all forced air commercial and industrial hvac systems.
Electric duct heater scr control.
Indeeco s attention to detail and rigorous testing give worldwide customers premium products that they receive quickly and at a fair price.
Upon restoration of power the step sequence resumes.
Not only does this give maximum control of your heat process but it can extend heater life many times over other control methods.
This duct heater features.
An electronic step controller provides electronic sequencing control of an electric duct heater up to 12 steps.
This gives smooth infinitely variable application of power to the heaters.
These controls proportionally turn on a percentage of each power line half cycle.
A transformer with any overcurrent protection required by ul or the nec to supply the internal control circuit of 120 volts per heater with a step controller for vernier control and 24 volts for all other heaters with scr control.
Price electric coils are factory mounted etl listed to meet electrical safety standards and comply with dual designation csa 236 ul 1995.
Useful for electric reheat and supplemental electric duct heaters.
Their applications vary from a partial or auxiliary nature to being the major or principal heat source in a building.
The scr control can deliver electrical power to heaters in several ways.
Heavy gage g60 construction with hinged access cover.
Since the scr is solid state it.
Scr power control in depth.
Automatic reset thermal safety switch for primary over temperature protection.
Fuses to protect each circuit in any heater drawing more than 48 amps.
Capacity and stages are dependent on voltage phase and heater dimensions.
A silicon controlled rectifier scr is a solid state switching device which can provide fast infinitely variable proportional control of electric power.
When interruption of power occurs all stages cycle off.
Manual reset thermal safety switch for secondary over temperature protection.
Viconics r820 scr power controller has been designed for safe and reliable control of electric heat loads.
Power and control terminal boards.
Electric reheat coils are an available accessory for use with price single duct and fan powered terminal units.
Standalone coils supplied as duct heaters are certified in compliance with ul 1996.
Scr power controllers are designed for an accurate and cost effective way to modulate electric heat.
